MACHINE FOR CLEANING AND SMOOTHING SILK AND OTHER THREADS.

SPECIFICATION forming part of Letters Patent No. 233,156, dated October 12, 1880.

Application filed December 10, 1879.

To all whom it may concern Be it known that we, ELIsHA J. MARTIN, of Rockville, in the county of Tolland, and ED- WARD TAYLOR, of Warehouse Point, in the county of Hartford, and State of Connecticut,

have invented certain new and useful Improvements in Machines for Cleaning and Smoothing Silk and other Threads; and we do hereby declare that the following is a full, clear, and

Jo exact description thereof, whereby a. person skilled in the art can make and use the same, reference being had to the accom panyin g drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

Our improvements relate to such machines as are intended for the purpose of removing any projecting fibers from the thread after it is spun, and for cleaning, polishing, and finishing the thread ready for use.

Our invention has for its object the more rapid and perfect accomplishment of the cleaning and smoothing process, and the simplification of the machinery by which it is performed; and it consists in the construction and arrangement of the mechanical devices which will be hereinafter described.

In the accompanying drawings, Figure 1 is 0 a side View of a machine embodying our improvements. Fig.2 is a top view of the same.

A is the frame of the machine. B is a box carrying the cleaningspindles C, &c. D is a bobbin containing the silk or thread which is 5 to be cleaned and finished.

E is a roller, around which the thread passes one or more times. The friction of this roller regulates the tension upon the thread, and is adjusted by a central screw or other common 0 device to give it the proper resistance.

The thread passes around the spindles C C C C, making several turns around each one, three being the number of turns usually employed, but a greater or less number may be 5 used. The thread then passes onto the roller F, around which it also makes several turns, and which may be called the drawing-roller, as it gives the motion to the thread. This roller receives its motion by a belt from a pulley upon the main shaft, which gives motion to the machine.

G is the bobbin which takes up the silk or other thread after it has passed through the cleaning process. It receives its motion from a friction-pulley, upon which it rests, so that its circumference has a tendency to run a little faster than that of the roller F. This keeps the thread always tight. For this purpose the axes of the bobbin G move in grooves in the frame of the machine, and it is fur- 6o nished with a weighted roller, H, which runs upon the circumference of the friction-pulley I, which communicates motion to it. This pulley I is driven by a belt from the main shaft, and at such a speed that the circumference will slip a little upon the roller H in keeping the tread tight.

J is a pulley upon the main shaft, which communicates motion to the pulleys F and I by means of belts, as before described.

The spindles C, &c., have hearings within the box B, as shown in the drawings.

It is designed to have a series of the machines hereinbefore described arranged side by side upon the same frame and driven by the same main shaft, so that a great number of threads can be operated upon at the same time. The number of cleaning-spindles can also be varied to suit different kinds of threads, eight being a suitable number for ordinary Silk.

The operation of our improved machine is as follows The thread being placed upon the machine as described, the roller-F draws it off from the bobbin D and revolves the roller E and the spindles C, and as fast as it is drawn forward it is taken up by the bobbin G. The thread is cleaned and finished by the operation of the spindles. The coils of thread roll upon the projectingfibers of the adjacent coils and cut them off or detach them from the body of the thread in such a manner as to leave them clean and smooth.

What we claim as our invention is 1. The combination of a series of stationary 5 cleaning-spindles, C, with the tension-roller E and the drawing-roller F, substantially as herein described.

2. The combination of the drawing-roller F, and the winding-bobbin G, substantially as 10 the winding-bobbin G, and the friction-pulley herein set forth.

I, with a pulley, J, upon the main shaft, constructed and arranged so that the circumfer- 5 once of the bobbin tends to turn faster than the drawing-roller to keep the thread tight, substantially as herein described.

3. The combination of an independent drawing-roller, F, with the stationary spindles C l ELISHA J. MARTIN. EDWARD TAYLOR. Witnesses:
